Some operating systems that are available for free include Linux Mint, Ubuntu, Elementary OS, openSUSE and Fedora. Each of these operating systems are based on Linux, a free and open-source operating system designed to be an alternative to Microsoft Windows and Apple Mac OS maintained by the community.
Linux-based operating systems are each designed with different goals and use cases in mind. Linux Mint, Ubuntu, Fedora, openSUSE and Elementary OS each aim to be a general-purpose operating system that the average user can learn and use as an everyday operating system. The primary difference to the end-user between distributions include the graphical user interface, software management system and bundled software. Linux distributions cannot run Windows software natively but are capable of running some Windows software using a package called WINE.
